Apparently you get about 10 or 12 sticks (hs and bs, HB to 8B I suppose) but these are good value - they are like a very thick version (more variety in the line quality and stroke) of the lead in a normal pencil - it's not lead of course but you'll feel the difference in the weight all the same. Evans can be found just in off Marys Abbey road(the luas runs along this street if that helps) off Capel Street. Website here:
Thanks to Carey for this info.
